SAW-TABLE GAG E.

SPECIFICATION forming part of Letters Patent No. 449,369, dated March 31, 1891. Application tiled April 3, 1890. Serial No. 346,504. (No model.)

.To all whom it may concern: Beit known that I, RUDOLPH KUEHNE, o

Milwaukee, in the county of Milwaukee, and

in the State of lVisconsin, have invented certain new and useful Improvements in Saw Table Gages; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to mechanism forshil'ting the work during the operation of sawing curved forms, such as stair-rails and similar articles and my invention consists in certain peculiarI and novel features of; construction and arrangement, as hereinafter described, r 5 and specifically pointed out in the appended claims.

In the accon'ipanying drawings, Figure lis a plan view of a saw-table-gage mechanism constructed in accordance with my invention. zo Fig. 2 is a view of the same, partially in end elevation and partially in section. Fig. 3 isa vertical longitudinal section of the same on the line 3 3 of Fig. 1. Fig. 4 is a transverse vertical section of the same on the line el 4: of Fig. l. Fig. 5 is a side or edge view of a portion of the sawtable, showing the form of attachment of its removable section. Fig. 6 is a detached sectional view of a portion of the saw-table, showing oneof its pivots.

In the class of work to which my invention relates the work has to be accurately changed relative t-o the cutting-face of the saw, so that the latter shall follow precisely the lines necessary to turn out the work in the re- 35 quired form.

The objects of my invention are to produce a machine which shall automatically effect these changes in the position of the work, or,

in other words, of the stick or timber being 4o operated upon by the saw, and which shall be simple in construction and direct 1n its action,

and the parts of which can be readily man1pulated to effect necessary changes in the operation of the machine. These objects I attain by the construction which I will now proceed to describe.

In the drawings, A designates the guidetable, which is of oblong rectangular shape, as is best shown in Fig. 1. The rear end of the 'guide-table is, however, cut away in segmental outline, so as to form the circular'recess a,

and from the center of this recess extends a straight inlet a', projecting toward the front end of the guide-table and having its sides parallel with the sides of said table.

B designates a removable section which forms the rear end of the guide-table and the front edge of which is cut on segmental lines to fit the circular recess a in the rear end of the table. At its center the removable section B is formed with a straight tongue l), which fits within the inlet a', but which is'shorter than the latter, and the extreme end of this tongue is bifurcated to form a recess b', for a purpose to be presently explained. The space between the inner end of the inlet ctand the outer extremity of the tongue l) is filled by a block c, the outer end or side of which is formed with a recess c', which matches the recess b in the tongue h when the block and tongue are in operative position, and supported bya plate e3, secured to the under side of the guide-table A by screws c2 or otherwise.

D designates the saw, which is of the band or jig type, as preferred, and the purpose of the construction thus far described will be understood when it is explained that in setting up the machine the guide-tableis brought rear end foremost toward the saw, so that the latter is caused to enter theinlet c. The block c is now placed in position, with the saw extending partially into its recess c. The removable section B is now placed in po sition at the rear end of the guide-table, with its tongue protruding into the inlet a and with the saw extending partially into the recess h at the extremity of the tongue. It will thus be seen that the saw is properly inclosed on all sides and the guide-table may be readily removed from the saw without necessitating any disturbance of the saw itself. When in position relative to the guidetable A, the removable rear section B is secured to the table by bolts or screws e, which g5 are inserted through the extreme rear ends of the table and enter the sides of the removable section B, as is best shown in Fig. 1. These bolts may obviously be readily de-v tached when the section B is to beremoved. roo

The guide-table A is pivoted so as to tilt laterally, as' hereinafter more fully described,

. n-ection between the guide-table and its standat the points indicated bythe letters y] in Fig. l. v

ff in Fig. 3 designate the pivot-supports, each of which occupies a vertical position, and the upper end of whichis reduced to an `edge. It is necessary that the pivotal conards should be practically coincident' with the upper surface of the table, so that there shall be no appreciable variation of the top surface of the table at the point where it coincides with the cutting-edge of the saw. In order to insure this result,I attach to the under side of the table a pair of bearing-plates G, each of which is formed with an indentation g at its bearing-point, and which at such point preferably projects through the table, asbest shown in Fig. 6. Thus the pivotal bearin gs of the guide-table are brought practically Hush with its upper surface, and the variation before referred to is reduced to the minimum. Beneath the guide-table at each of its pivotal bearing-points is secured a segmentally-slotted sectorIvLwhich extends close to one side of the adjacent pivot-standard for f. A guidebolt h, which extends through the slot of the sector, is attached to the adjacent portion of the pivot-standard, and the arrangement is such that as the guide-tableA tilts the bolts prevent anydisplacement of the table from its pivot-bearings. It is obvious thatany desired number of these pivot standards and bearings may be used; but, as shown, the t-wo standards f f are formed integrally with a horizontal base F, which is suitably secured to the sawtable A by clamping-screws q or otherwise.

At the front end of this base F are formed two oblique horizontal rearwardly-extending sockets I, opening from opposite sides of the base. Within one or the other of these sockets I is removably inserted one end of an elongated base-barJ ,which thus extendsoutwardly and rearwardly from the table A, as shown in Fig. l. At its outer end the base-bar J carries a vertical standard K, upon which is pivoted one end of a swinging bar L, the opposite end of which normally extends beyond the rear end of table A.

M designates a chain,iope,or other flexible connection, one end of which is attached to the table A beneath one side of the same, and which runs thence beneath a pulleyj on the base-bar and against a pulley n, journaled in the upper part of a standard N, which rises' vertically from said bar. The opposite extremity of t-hechain M is passed through one or another of a series of holes 7e in bar L, near its pivotal connection with the standard K.

A weight O is removably attached to one or the otherI side of the table A by screws o, as required, and it will be seen that when the work is passed back beyond the saw it will strike the free end of the swinging bar L and move it away from the rear end of the table. This movement of the swinging bar L Vdraws upon the chain M and tilts the table laterally toward the outer end of base-bar J, thus giving the work the required inclination relative to the saw to produce the required curved cut. The weight O depresses the table A as soon as the swinging bar L is released, and also returns said bar to its normal position. (Shown in Fig. l.) lVhen the pattern requires a cut of an opposite curvature from that given by the parts arranged as above described, the base-bar J, with its bar L, is removed f rom the left-hand socket I and placed in the corresponding right-hand socket (with the bar J in the left-hand socket I) and the arm L is swung around so as to extend oppositely from the standard K. Thus the table Awill be tilted in the opposite direction from that. described when the end of the work strikes the swinging arm L.

J designates a bar which is shorter than the base-bar, and which is removably set in the opposite socket I from 'that in which said base-bar may be set. This bar J. is provided with a vertical post j', which, when the swinging arm L is released from the work, thelower side of the table strikes, so that the table is thus prevented from descending beyond its normal horizontal plane.

In order to retain the base-bar in proper position, its upper side is engaged by a clamping-arm p, which is pivoted to a base P, the latter being in turn secured yto the saw-table A One of these clamping-arms is located at each side of the machine, so as to retain .the base-bar at either side of the table. The standard K is set ina socket 7a, so as to turn therein, and the swinging arm L is held adjustably upon the standard by a set-bolt k2, thus permitting the swinging arm L to'be varied in vertical position relative to the table A, as may be required by different classes of work.

In order that the movement of the swinging arm L by contact with the end Vof the work may be varied to exactly accord with the pattern or form to be produced, a plate or board R is set upon the upper side of the free end of said arm, and said plate or board is provided with transverse slots r, through which clamping-screws s are inserted and err ter the adjacent upper sideof the arm.. AThus it will be seen that by varying the position-of the plate or board R transversely upon the free end of the arm L, the work will come into contact with and swing the arm at a'less or greater interval ofV time after having passed the saw, and thus the table willbe tilted at the exact moment necessary t-o vgive the de= sired cutto the work.

T designates an Varm which projects horizontally from the rear end of the guide-table and which supports the free end of the swing ing arm L when the same is movedaway from the table by the work. At its inner end `this supporting-arm is formed with an open slot and with an eye-slot t', which slots receive the screws e e, respectively,'at either side of the guide-table and securely ret-ain the guide-'bar IOC IOS

IIO

in properposition, while permitting its ready removal.

It will be obvious that by setting the free end of chain M nearer to or farther away from the fulcrum of the swinging bar L (which the holes k permit) the table will be tilted sooner or later or more or less after the Work comes into contact with the free end of the bar L, and thus further exactness of the cut is attained.

It will thus be seen that I have produced a simple and effective machine for this class of work and one which is readily manipulated to effect all of the adjustments necessary to the .requirements of the work and the operation of which is direct and entirely automatic.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a sawing-machine, a laterally-tilting guide-table, in combination with a swinging` arm extending normally across the path of the work on said table, and connections, substantially as described, for causing the movement of the arm to tilt the table, for the purpose set forth.

2. In a sawing-machine, a laterally-tilting `guide-table, in combination with a swinging` arm extending normally across the path of the work on said table, and a flexible connection between the table and the swinging arm, substantially as described.

3. In a sawing-machine, a laterally-tilting table, in combination with a reversible swinging arm arranged to extend normally across the path of the work from either side of the table, and a flexible connection between the arm and the table, substantially as set forth.

4. In a sawing-machine,a counterweighted laterally-tilting guide-table, in combination with a swinging lever extending normally across the path of the work on said table, and a exible connection between said arm and table, substantially as described.

5. In a sawing-machine, a laterally-tilting guide-table, in combination with a swinging arm extending` normally across the path of the work on the table, and a flexible connection between the table and arm adjustably connected to the latter, substantially as set forth.

G. In a sawing-machine, a laterally-tilting guide-table, in combination with a swinging lever extending normally across the path of the work on the table and having an adj ustable section against which the work abuts to tilt the table, substantially as described.

7. In a sawing-machine, a guide-table constructed in two sections, one of which is cut inward at its rear end to receive the outwardlyextending end of the opposing section, the latter having a recessed tongue to enter a corresponding inlet of the first-named table-section, and thus removably inclose the saw, substantially as set forth.

8. In a sawing-machine, a laterally-tilting table, in combination with a removable swinging arm arranged to extend normally across the path of the work, a flexible connection between the arm and the table, anda bar removably set on the opposite side ofthe table and having a stop to limit the tilt of the latter, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
